Read full description

nAble OnCall provides a quick and easy way to setup a call schedule for a group of physicians at one or more healthcare facilities. With a simple and intuitive layout, nAble OnCall follows the familiar process of creating a call schedule. The call schedule administrator creates a call group, invites members to join the group and asks for their call preferences. Aided by the nAble OnCall and the input from the group members, the administrator creates an equitable call schedule. The group members can send messages within the group to request call swaps or seek temporary coverage arrangements. The call schedule is displayed in color-coded format on a monthly calendar, which can be shared, emailed, and printed.
